My hope is that the major players here, particularly the Liberals and NDP, can come together to find ways to negotiate to find a compromise electoral system that they can all live with. I discuss a potential way to do that here, using a system with “tunable” proportionality.
The systems currently being discussed, such as MMP and IRV (allegedly favored by Trudeau), are unfortunately rather antiquated, having been invented decades before most of the major advances in social choice theory (e.g. Arrow’s Theorem, the Gibbard-Satterthwaite Theorem). Warren Smith is a Princeton math PhD who co-founded the Center for Election Science and was the protagonist of the groundbreaking book Gaming the Vote. He has proposed a number of modern electoral systems specifically designed to meet Canada’s needs and correct defects in those older systems.
It’s very esoteric, but important material. You should put at least as much science and engineering into your electoral system as you’d put into your aircraft or web sites.
